DTC Codes

DTC is a Diagnostic Trouble Code that is used to diagnose the problem in any vehicle.

A DTC code is a set of diagnostic issue codes that a vehicle’s onboard diagnostics (OBD) system uses to notify you when it detects a problem. Different DTC codes indicate various issues with your car.

Types of Codes

There are over 1000 generic and manufacturer-specific DTC codes that may air on your car. It is quite difficult for everyone, even technical experts, to acknowledge all the fault codes.

If you are unable to recognize DTC codes even after going through the manufacturer’s manual, ask for some professional help.

Generally we can classify DTC Codes into two main groups.

• Critical Codes: DTC codes that may result in sudden and intense damages to the vehicle and demand quick action. These may include low coolant level or high engine temperatures which indicate that engine failure is very much on the cards.
• Non-Critical Codes: Non-Critical DTC Codes may not demand quick remedies, but they need proper attention. Emissions problems which may not lead to intense pollution fall in this category.
